I'm dictating this post using speech recognition in Windows Vista. So without touching any keys. It works remarkably well. I find this the most impressive feature in Windows Vista I've seen so far. The computer is still getting used to my voice, so I have to correct some words. You don't even have to touch the keyboard to correct words. You can move the cursor using voice commands. I could even assign categories to this post by calling out "show numbers" and choosing user interface elements by calling out the number that is then displayed over the element.
If you are running Windows Vista and have a microphone try this out by running the speech recognition tutorial. Press the start button and type "speech recognition" in the search box to find it.
That is all for now. It does take getting used to and I'm getting tired.
